Duo Security, now part of Cisco, is the leading multi-factor authentication (MFA) and Zero Trust Security solutions provider.


Our mission is simple: democratize security by making it easy and effective for everyone. We’re transforming security from the ground up by solving the world’s most pressing geopolitical challenge — safe, secure information access through Zero Trust Security solutions. We use a human-centric product design approach to reduce the complexity and create solutions that are simple to use.


Our work culture is defined by values of “Being kinder than necessary”, “Learning together”, “Engineering the business” and celebrating the diversity of perspectives. A positive and intellectually nurturing environment for employees is the reason Cisco has won the “Best company to work for” three years in a row* and earned us the title of “The most loved security company” given by our customers.


We invite you to join our growing Platform Engineering group to create the systems that are foundational in supporting our rapidly expanding global customer base.


We believe in providing opportunities to our team members to work on various aspects of our service from the platform architecture to end-user-facing features. This mobility helps them build their skills and develop empathy for our end users resulting in a best-in-class product. When you join the Platform Engineering group you will be paired with a team that matches your interests and skills. As your interests evolve you will have the opportunity to experience and contribute to other areas within our group.

The teams within the Platform Engineering group have three distinct focus areas:

Duo Administration: Building the service and features that are used by end users to configure and deploy the Duo service to implement Zero Trust Security in their environment. This team is embarking on an exciting journey to completely redesign the administration experience for our customers on a new platform they are building.

Customer Systems: Building systems for a global Cisco workforce for managing Duo customers, generating data flows to feed the business intelligence workflows and improving the customer experience with e-commerce platforms through which they transact with Duo. This team is working on an exciting opportunity to create a product experience that will enable Managed Service Providers (MSPs) to scale up their customer base.

Platform architecture: Creating application-level platform solutions like additional levels of security for asynchronous integration of services based on Kafka and SQS, intelligent rate limiters for endpoints, and various services used by end users and other product teams to build out Zero Trust Security solutions.
